产品概述
The TPS2459 hot-plug controller performs all necessary power interface functions for an
AdvancedMC™ (Advanced Mezzanine Card). A fully integrated 3.3-V channel provides inrush control,
over-current protection, and FET ORing. A 12-V channel provides the same functions using external
FETs and sense resistors. The 3.3-V current limit is factory set to AdvancedMC™ compliant levels
while the 12-V current limit is programmed using external sense resistors. The accurate current
sense comparators of the TPS2459 satisfy the narrow ATCA™ AdvancedMC™ current limit
requirements.
